At his approach the princess rose from her seat. The two factions perceiving her action, and curious to learn what she would say, ceased their raging.

"Marshal Zabern," cried Barbara in a voice that sounded like music after the raucous clamor of the previous few moments: "I call upon you to re-arrest that escaped prisoner, and to conduct him to the Citadel."

"You threaten me with imprisonment?" exclaimed Bora with a stern air. "It is mine to threaten, and yours to fear. People of Czernova," he continued, turning from the choir to address the assembly, "hear a revelation, strange yet true. She who sits there has no right to the crown, inasmuch as she is not Natalie Lilieska, but an impostor bearing a marvellous resemblance to that princess. The true Natalie died in Dalmatia more than two years ago."

The duke's words destroyed Zabern's lingering hope that Ravenna's letter might have miscarried, for how had Bora become possessed of his present knowledge, except through the medium of the cardinal's dove?

"Marshal Zabern," continued the duke, pointing to Barbara, "I call upon you to arrest an impostor who usurps my throne."

"And you may call," replied Zabern.

The duke's statement drew derisive laughter from the Poles; it was too absurd for belief, a malicious invention of a disappointed suitor. At this point Polonaski the Justiciary, who occupied a seat directly fronting the choir, arose and addressed the princess.

"Lady," he began, and showing by that word that he, too, like Mosco, had taken the side of her enemies, "lady, you have heard the duke's accusation. Let this assembly learn from you whether the charge be true."

It was hard for a youthful and spirited princess to be catechised by a minister who had suddenly turned against her.

"Your Highness, do not answer the traitorous gray-beard," said Zabern.
